Package: [http://www.samsung.com/global/business/semiconductor/support/PackageInformation/downloads/SystemLSI/FBGA/232_FBGA_1010_12_05.pdf 232-pin FBGA 10x10mm] or 224/226-pin 9x9mm. Similar chips: [http://www.samsung.com/global/business/semiconductor/productInfo.do?fmly_id=212&partnum=SA58700 SA58700X07]. Some documentation available for the S5L series can be found [[S5L8700 datasheet|here]]. The processor itself is Apple-branded and marked 337S3291 8701.
